Reflection - class viewer - jd-gui

[moster67]

It seems like reflection is possible also with Java although I am not sure if actually an Android apk-file can be decompiled.

In any case, I found a utility called JD-GUI which can be used for opening jar-files such as the wrapper-libraries found in the library-folder of B4A. You can find JD-GUI here:

JD-GUI | Java Decompiler

Yes JD is very useful to view objects in the class files, as for de-compiling the dex files in apk install packages (apk are zip files structured) there are none, it is compiled into a byte code language for the Dalvik vm, very interesting reading, much faster than jvm.

dedexter can do it

Actually there is a solution for DEX files: dedexter. You can find it at dedexer.sourceforge.net.

It is not 100% perfect solution but you can use it with JD-GUI and get Java source from your Android APK files.
